front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late. In this or similar situations, the automatic high-
beam headlamps will not be deactivated or
activated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. Youare responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured

!
Do not operate the windshield wipers
when the windshield isdry, as this could
damage the wiperblades. Moreover, dust
that has co llected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wiper sin dry weather conditions, always
use washer fluid when operating the wind-
shield wiper s.
!Ifthe windshield wipers leave smears on
the windshield after the vehicle has been
washed inan automat iccar wash, wax or
other residues may bethe reason for this.
Clean the windshield using washer fluid
after washing the vehicle inan automat ic
car wash.
!In term ittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirtyin dry weather conditions,
the windshield wipers may beactivated
inadvertently. This could then damage the
win dshield wiper blades or scratch the
win dshield.
For th isreason, you should always switch
off the windshield wipersin dry weather.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
RYou should therefore drive at varying vehi-
cle and engine speeds for the first
1000 miles (1500 km).
RAvoid heavy loads, e.g. driving at full throt-
tle, during this period.
RWhen changing gears manually, change up
in good time, before the tachometer needle
reaches Ôof the way to the red area of the
tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RTry to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program E.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate
the vehicle to full speed.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the maximum permissible
speed.
Driving
Important safety notes
